-041 BLACK BUNA 50D O-RING

Part number H50041 is an AS568-041 black Buna-N (Nitrile) 50 Shore A O-Ring supplied with an inside diameter of 2.989 in (75.92 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 3.129 in (79.48 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

This material stands up to greases and lubricants, petroleum-based oils, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) delivers strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It is not the right choice where strong acids or ozone and direct sunlight are present.

You will find this material specified across hydraulic and pneumatic systems, construction equipment, and automotive.
